Medical Imaging

Physicians utilize medical imaging to see inside the body to diagnose and treat patients. This includes computed tomography (CT), magnetic resonance imaging (MRI), X-ray, ultrasound, fluoroscopy, angiography, and the nuclear imaging modalities of PET and SPECT.

Breast cancer screening rates saw a 10% drop among several groups of women over the last 2 decades
Decreased screening rates among different subgroups highlight the ongoing need for outreach strategies that target vulnerable populations, experts contend.
Northwestern deploys new mobile stroke unit equipped with 32-slice CT scanner

Department of energy partners to bolster domestic radioisotope supply
Gadolinium-153, or Gd-153, is routinely used to calibrate nuclear imaging equipment. It has been in short supply since 2023 when global distribution of the radioisotope came to a halt.

SPECT technique might measure absorbed tissue dose from radiation therapy

Washington University is using a novel low-count quantitative SPECT technique to measure the concentration of alpha particle radiopharmaceutical therapy activity in the tumor and in radio-sensitive organs.

Sean Fain, PhD, vice chair of radiology and research and a professor of radiology, Division of Cardiovascular and Thoracic Imaging, University of Iowa, discusses how long-COVID lung damage can be tracked using xenon (Xe) gas magnetic resonance imaging (MRI) and quantitative computed tomography (CT). He spoke to Health Imaging at RSNA 2022.
